What is a TBI?

A TBI is a disruption of normal brain function caused by trauma. Traumatic brain injury is categorized as mild (concussion), moderate or severe.

What causes a TBI?

Traumatic brain injuries are caused by a blow or jolt to the head or a penetrating object. Other injuries are caused by a rapid acceleration or deceleration of the head, which can force the brain to move back and forth inside the skull.

The leading cause of TBI is falls, followed by motor vehicle crashes (car, motorcycle, ATV, etc.), being struck by or falling against an object, and assault.

  • Slowness in thinking, speaking, acting, or reading
  • Getting lost or easily confused
  • Feeling tired all of the time, lack of energy or motivation

  • Blurred vision or eyes that tire easily
  • Loss of sense of taste or smell
  • Ringing in the ears
